17:42 <m4110c> Hi, I have a short question regarding a helper function call. I have a recursive function that receives a list as a parameter, but needs to use the reversed list in its body. If I write a helper, that returns the reverted list, it will revert the list again on each recursion through the main function...how can I achieve, that the helper is called only once in the main recursive function?

17:46 <m4110c> e.g.: if I give the helper (list 1 2 3 4), and recursion starts, my main function will finally have gotten back (list 4 1 3 2) but I want (list 4 3 2 1)

17:51 <m4110c> no one?

18:01 <lexi-lambda> m4110c: Your question sounds like it’s come up during homework. Perhaps you’d be better served by asking an instructor and/or attending office hours?

18:02 <m4110c> yeah, but it's not. I'm trying to learn functional programming and I just can't get my head around this simple problem

18:02 <m4110c> what is the correct way, to call a helper only once in a recursive function?

18:03 <m4110c> not possible, hum?

18:04 <lexi-lambda> It is certainly possible. What resources are you using to learn?

18:05 <m4110c> the racket documentation and google :-D

18:05 <lexi-lambda> Consider looking at HtDP: https://htdp.org/2018-01-06/Book/

18:06 <m4110c> ok, I'll do so, thanks

18:51 <badkins> I'm trying to nest a @codeblock within a @para to no avail. Just started looking into Scribble today, so very much a newbie: https://gist.github.com/lojic/a3ebb2df02128e562cd60483ed146268

18:52 <badkins> Looks like @para is expecting "pre-content?", so I gather @codeblock does *not* produce pre-content?

19:06 <badkins> All I really want is to have control over indentation/spacing and place w/in a "box"

19:07 <badkins> Similar to this doc: https://jsonapi.org/examples/

19:30 <badkins> I suppose @verbatim would be better than @codeblock, but I'm still at a loss as to how to include that w/in a boxed paragraph.

19:36 <badkins> Looks like @nested will do what I need: https://gist.github.com/lojic/a3ebb2df02128e562cd60483ed146268

19:47 <daftpunk> m4110c: use locals

20:40 <m4110c> daftpunk: thanks a lot!
